Application filed July 1, 1915. Serial No. 37, 525v To all whom it mayconcern:

Be it known that I, WILLIAM 'F. Ynnenns,

a citizen of the United States, residing at,

Huntington, in the county of Huntington and State of Indiana, haveinvented certain new and useful Improvements in Valves; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in valves and more particularlyto what are known as quick acting balance valves.

The object of the invention is to provide a valve of this character soconstructed as to be perfectly balanced for preventing any possibilityof pressure on either side from opening the valve and which is operatedby a lever, thereby dispensing with the usual screw gear.

With the above and other objects in view, the invention consists ofcertain novel features of construction and in combination andarrangement of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 represents a side elevation of avalve constructed in accordance with this invention; Fig. 2 is avertical section thereof; Fig. .3 is a horizontal section taken on theline 3-3 of F ig. 2; Fig. 4: is a similar view taken on the line 44 ofFig. 2' with the valve shown open; Fig. 5 is a similar view with thevalve closed; Fig. 6 is a plan view with the valve removed; Fig. 7 is adetail perspective view of the lower end of the valve stem; Fig. 8 is asimilar view with the valve in position thereon; and Fig- 9 is a detailperspective view of the valve detached showing the lower end thereof.

In the embodiment illustrated, a hollow cylindrical valve casing 1 isshown having alined coupling members 2 and 3 arranged to communicatewith the casing and prefer ably cast integrally therewith and opening,

into said casing at oblique angles, the passages or conduits 4 and 5which connect the openings in the couplings with the valve casing beingarranged in planes substantially at right angles to each other, theopening 4 being in the form of a compound curve, and the opening 5 beingobliquely disposed in relation to the coupling 2 with which itcommunicates. A socket 6 is arranged centrally in the bottom 7 of thevalve casing and a concentric arcuate seat 8 is formed in said bottomfor a purpose to be described.

A substantially cylindrical valve 9 fits within the cylindrical bodyportion of the casing land has anangular bore or channel 10 extendinglongitudinally therethrough and which is designed to receive acorrespondingly shaped valve stem 15, said stem having its lower endrounded as shown at 16 to fit within the socket 6 of the casing whichforms a bearing for said stem. The opening 10 which extendslongitudinally through the valve 9 opens through one'side wall thereofas shown at 11 and said side wall through which this opening extends, isrecessed as shown at 12, thereby providing two pairs 'of upper andlowerlugs 13 and 14 at the upper and lower ends of the valve, saidrecess forming a space for permitting the fluid controlled by the valveto pass when the valve is properly turned to bring said recess intocommunication with the openings it and 5 of the casing. This valve isprovided on its lower face with an arcuate rib 9 which is adapted toproject into the segmental groove 8 in the casing bottom and which isdesigned to abut against opposite ends of said groove for limiting theopening and closing movement of the valve to provide for said valvebeing opened and closed to its full extent only and to prevent itspassing beyond these points. The outer face of the valve 9 adjacent oneside of the recess 12 is cut away to form a pressure chamber 9 which isof a length equal to the distance between the inner faces of the upperand lower lugs 13 and 1.4.- adjacent which said chamber is formed. Thischamber 9 tapers in a direction extending away from the recess 12, thusforming when the valve is in operative position within the casing achamber for relieving the pressure. on thevalve and permitting.it to bedistributed around the valve except that portion which covers theopening when the valve is closed.

The angular portion of the valve stem 15 which fitswithin the bore orchannel 10 in the valve is designed to connect the valve with the stemand adapt it to be turned therewith when the stem is rotated. This stem15 is also provided on its outer face of its upper and lower ends withlaterally extending shoulders '17 and 18, the inner faces of whichregister with the inner faces of the lugs 13 and 14. The stem above theangular portion 15 is made round to adapt it to turn within a closure 19which is shown in the form of a nut, the lower end of which isexteriorly threaded and screwed into an opening 1 in the top of thecasing, said closure being provided with an annular flange 20 whichabuts the casing around the opening 1. As shown, this nut has the usualangular portion arranged above the flange 20 designed to receive awrench for removing and inserting the nut when desired. A cap' 21surmounts the nut 19 and has a packin 21 arranged between it and the nutaround the valve stem 15 to insure a fluid tight connection. The upperend of the valve stem is made angular as shown at to receive anoperating handle 24: which may be held thereon in any suitable ordesired manner, said handle operating as a lever for turning the valvestem to open and close the valve.

From the above description, it will be obvious that when the valve isinserted within the casing with the stem 15 arranged in operativeposition therein, it will be equally balanced so that pressure on eitherside thereof cannot open it, the operation of the valve being obtainedby revolving it around its own center by means of its stem 15,,therebeing no screw or screw gear necessary to accomplish this purpose.

It is of course to be understood that this valve may be of any suitableor desired size and constructed of any suitable or desired material andthat it may be used for any kind of fluid, gas, steam or air and willoperate equally well when used in connection with any of them.

I claim as my invention:

1. In a valve, the combination .of a hollow cylindrical valve casinghaving alined coupling members with passages communieating with thecasing at oblique angles and arranged substantially at right angles toeach other, said casing having a socket arranged centrally in the bottomthereof and said bottom provided with a concentric arcuate groove, acylindrical valve mounted to turn in said casing and having an angularchannel extending longitudinally therethrough, a correspondingly shapedvalve stem having its lower end rounded to fit in said socket, saidvalve channel opening through one wall of the valve, said wall beingrecessed on both sides of the opening and forming two pairs oflongitudinally spaced lugs, an arcuate rib on the lower face of saidvalve positioned to enter the groove in the bottom of the casing, andbeing of less length than said groove, the ends thereof being designedto abut the ends of the groove to limit the turning movement of thevalve in opposite directions, and means for relieving the pressure onthe valve.

2. In a valve, the combination of a hollow cylindrical valve casinghaving alined coupling members with passages communicating with thecasing at oblique angles and arranged substantially at right angles toeach other, said casing having a socket arranged centrally in the bottomthereof and said bottom provided with a concentric a rcuate groove, acylindrical valve mounted to turn in said casing and having an angularchannel extending longitudinally there through, a correspondingly shapedvalve stem having its lower end rounded to fit in said socket, saidvalve channel opening through one wall of the valve, said wall beingrecessed on both sides of the opening and forming two pairs oflongitudinally spaced lugs, an arcuate rib on the lower face of saidvalve positioned to enter the groove in the bottom of the casing andbeing of less length than said groove, the ends thereof being designedto abut the ends of the groove to limit the turning movement of thevalve in opposite directions, the outer face of said valve adjacent oneside of the recess therein being cut away to form a pressure chambertapering away from the recess, thereby forming in connection with thecasing when the parts are assembled a chamber for relieving the pressureon the valve, permitting it to be distributed around the valve except atthat portion which covers the opening when the valve is closed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witne'sses.
